To all IO/tU'I/b it may concern:

Be it known that I, JoHANNUs M. GANT- voom, a subject of the Queen of the Netherlands, residing at Fishkill Landing, in the county of Dutchess and State of New York, have invented new and useful Improvements in Baking Apparatus, of which the following is a specification.

This invention relates to an apparatus for charging and emptying baking ovens.

In the art of baking many kinds of pan goods, such as bread, the dough, after being shaped or molded, is put into pans, the pans put into a rack, the rack rolled into a proofing room where the dough is proofed." the rack then rolled to the oven, and the pansremoved, one-by-one, from the rack and inserted into the oven. After baking, the pans are again individually removed from the oven and emptied or placed back into the rack to allow the bread to cool. This procedure is sometimes varied in filling and emptying draw plate ovens, but in any event each pan is handled at least twice. involving the cost of a great deal of time and labor.

The object of my invention is to provide a novel charging and emptying structural means, whereby a greater portion of such time and labor will be saved, the amount of labor reduced and the work facilitated to a material extent.

The invention consists in the novel steps, features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which Figure 1 is a vertical front-to-rear section through a baking oven embodying my invention. Fig. 2 .is a vertical transverse section of the same. Fig. 3 is a sideelevation of the rack. Fig. l is av transverse section of the same. Fig. 5 is a view, showing the rack and oven arranged for transfer of the trays from one to the other.

In carrying my invention into practice, I provide a baking oven 1 having a series of superimposed baking spaces 2; In each space are bars or T-irons 3, supporting a plurality of steam heating pipes l. The open front end or mouth of each oven chamber is normally closed by an inwardly and upwardly swinging door 5, and extending described, into and .out of the respective 1 oven spaces. The heat supplying pipes 4 extend through the rear Wall of the oven and into the fire box or combustion chamber 8 of the furnace, whereby the oven as a whole and the heating pipes are heated to the desired temperature. Within the base of the fire box is arranged a suitable grate 9, and at the top of the fire box is a ehim' ney outlet 10 controlled by a damper 11.

12 and 13 designate the fire box and ash pit door and 14 suitable cleanout openings closed by plugs or stoppers 15. The fur-. nace part of the oven structure may be of any suitable type.

For cooperation with the multiple oven of the type described, I employ a rack 16 mounted for transportation upon supporting wheels 17, said rack comprising a series of uprights 18, cross pieces 19 and longitudinal bars 20, the latter being formed of angle metal and constituting a series of super-posed pairs of track rails spaced the same extent apart as the tracks in the respective oven spaces or chambers and equal in number to said spaces. The track rails have extension ends 21 which are adapted, when either end of the rack is moved into abutting contact with the mouth of the oven, to engage the guide extensions 7 and bring the track rails of the rack into exact alinement with the track rails in the oven chambers for the transfer of the transportable oven floors, trays or shelves, as herein fully set forth, from the oven chambers to the rack or vice versa. The bread or other goods to be baked is placed in suitable pans which are supported in suitable skeleton or open frame work, baking floors, trays or shelves 22, each of which is mounted at each of its ends upon supporting wheels or rollers 23 adapted to travel upon the track rails 6 and 20 and to support the open work body of the floor or shelf above the fixed or stationary floors, of the oven chambers. In practice, the baktrays or shelves,

ked is molded into the desired shape and fix d placed in baking pans, which. pans are disposed within the transportable baking floors, which floors or shelves are arranged 1n superposed relation upon the rack. When therack is filled, it is drawn or outer end of the rack and tion is completed and the rack is ing open for pushed into the usual proofing room where the dough is proofed, after which the rack is transported to the mouth of the oven and one of its ends brought into proper relation to dispose the track rails thereon in registering alinement with the rails in the respective oven chambers. The floors are then pushed or rolled forwardly from the run along the rails into the oven chambers. The goods are then baked-in the ordinary way, the rack either beingremoved for other use or allowed to remain, in proximity to the-oven until the goods are baked. After the baking operaarranged 1n. proper receiving position, the doors of the oven chambers are successively opened and the transportable floors or shelves drawn out of the oven chambers into the receiving spaces in the rack, which, upon the oven be ing emptied, may be moved to one side and thekoven reloaded'with floors from another rac It will be understood, of course, that in the baking operation the shelves perform the function of the floors proper,'such floors bethe free passage of the heat to facilitate the baking operation, and that such floors are bodily msertible into and Withdrawable from the oven chambers for inter-transfer between said oven chambers and the rack. By this construction and arrangement of the parts, the necessity of individually removing the same is avoided, with economy in time and labor, as the shelves of the rack may be filled and emptied at convenient moments, and the pans maybe more readily and easily inserted therein and Withdrawn therefrom than is possible in the ordinary operation of charging and emptying an oven. My invention also secures all the advantages of the ordinary draw-plate oven without its disadvantages and insures a more rapid, convenient and labor-saving handling of the goods.

Having thus described the invention, I claim 1.
